PANews reported on April 8th that the decentralized stablecoin USDD announced the launch of two WBTC Vaults on the TRON network, allowing users to mint USDD using WBTC as collateral. This adds a premium collateral option to USDD's existing TRX, sTRX, and USDT Vaults, marking a further diversification of the protocol's collateral assets.

As the largest and most widely recognized Bitcoin tokenized asset by market capitalization, WBTC's inclusion significantly enhances the diversity and robustness of the USDD collateral pool. The newly launched WBTC-A and WBTC-B Vaults reportedly have minimum collateral ratios of 150% and 130%, respectively, with minimum borrowing amounts of $1,000 and $2,500. Users can also amplify their returns through two efficient strategies: first, leveraged long-term cycles, where users collateralize WBTC to borrow USDD and then exchange it for more WBTC on a DEX for further collateralization; second, cross-platform arbitrage, where users borrow USDD and deposit it into a high-yield mining pool to earn net interest spreads.

The USDD team stated that the launch of WBTC Vaults is an important step for the protocol to diversify its collateral assets, enhance security, and improve user experience, which will further strengthen USDD's market positioning as an "interest-bearing version of USDT".
